摘　　要：在深入分析传统步进电机单极性驱动方法和双极性驱动方法进行细分控制的基础上,提出一种针对两相六线步进电机的单极性细分平稳驱动方法。该方法采用在步进电机公共端与电源间串联P-MOSFET进行细分控制,在电机各相输出端与电源回线之间串联N-MOSFET进行通路选择的方式,消除了两相电机同轴绕制线圈之间的相互干扰,实现了两相六线步进电机的单极性细分平稳驱动。该方法不存在电源和地直通的风险,可在对可靠性要求较高的航天航空领域广泛应用。A unipolar subdivision stationary driving method for two-phase stepping motor was proposed im- proving stationarity and reliability of traditional driving methods. A P-MOSFET was connected between power supply and common port of motor for subdivision, and an N-MOSFET was connected between each phase line and ground for electrical current gateway selection. The mutual interference between A-phase and non-A- phase was eliminated by the proposed method, and unipolar subdivision stationary driving was realized. For there exists no direct access between power supply and ground, this method can be extensively used in space and airspace field.
